## Remarks An ordinary exception makes the job re-leasable immediately. A handler that wants backoff throws this instead; the background worker passes the [JobRetryException.RetryAfter](/api/tracon.jobretryexception/#Tracon_JobRetryException_RetryAfter) value into the [IJobStore.ReleaseForRetryAsync](/api/tracon.ijobstore/#Tracon_IJobStore_ReleaseForRetryAsync_System_Guid_System_String_System_Nullable_System_TimeSpan__System_Threading_CancellationToken_) call. The attempt count is still capped by [JobRecord.Attempt](/api/tracon.jobrecord/#Tracon_JobRecord_Attempt): this exception does not keep the job alive forever. ## Constructors ### JobRetryException\(\) Creates a new retry request. ```csharp public JobRetryException() ``` ### JobRetryException\(string\) Creates a new retry request. ```csharp public JobRetryException(string message) ``` #### Parameters `message` [string](https://learn.microsoft.com/dotnet/api/system.string) The error message. ### JobRetryException\(string, Exception\) Creates a new retry request. ```csharp public JobRetryException(string message, Exception innerException) ``` #### Parameters `message` [string](https://learn.microsoft.com/dotnet/api/system.string) The error message. `innerException` [Exception](https://learn.microsoft.com/dotnet/api/system.exception) The underlying error. ## Fields ### JobRetryErrorType The stable value written for [TraconException.ErrorType](/api/tracon.traconexception/#Tracon_TraconException_ErrorType). ```csharp public const string JobRetryErrorType = "job_retry" ``` #### Field Value [string](https://learn.microsoft.com/dotnet/api/system.string) ## Properties ### ErrorType Gets the stable error type name written to the run record. ```csharp public override string ErrorType { get; } ``` #### Property Value [string](https://learn.microsoft.com/dotnet/api/system.string) #### Remarks Defaults to the full name of the exception type, so today's behaviour does not change. A derived type overrides this member when the record has to be machine readable — for example [TraconContentFilteredException](/api/tracon.traconcontentfilteredexception/) writes `content_filtered`. Reports and alert rules can rely on this stable name instead of an assembly name. The value is written to `RunError.Type` and **carries no secret**. ### RetryAfter The time to wait before the next attempt. If [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null), the job may be re-leased immediately. ```csharp public TimeSpan? RetryAfter { get; init; } ``` #### Property Value [TimeSpan](https://learn.microsoft.com/dotnet/api/system.timespan)?
